The Arskartor Be-Nb-Mo deposit is the second largest Be deposit in the Chinese Altai, NW China, which hosts over 11,000 tons of BeO resource. The muscovite-albite granite and rare-metal pegmatite in the ore district are spatially and temporally coexisted and both are beryllium mineralized. The muscovite-albite granitic stock can be divided into a barren …

Beryllium and beryllium compounds were in 1971, 1979 and 1987 (IARC, 1972, 1980, 1987a). New data have since become available and these are included in the present monograph and have been taken into consideration in the evaluation. The agents considered herein include (a) metallic beryllium, (b) beryllium-aluminium and -copper …

With the crystallization of the main part of the Arskartor muscovite-albite granite, fluxes and incompatible elements especially beryllium were progressively accumulated in the late granitic melt (London and Evensen, 2002, Linnen et al., 2012), and generated the coarse-grained granite with Be-mineralization subsequently (Fig. 8 a).

Previous studies have shown that the JSB and its surrounding district contain the Sanjiang region's most important Cu–Pb–Zn–Au metallogenic belt, which is genetically associated with host granite plutons [1 – 3, 5, 6]. Therefore, obtaining accurate constraints on the nature and age of these ore-related GPs has a particular ...

Geochemistry, zircon U–Pb geochronology, and Hf isotope data for the Early Paleozoic granites in the Baoshan Block reveal the Early Paleozoic tectonic evolution of the Proto-Tethys. The samples are high-K, calc-alkaline, strongly peraluminous rocks with A/CNK values of 1.37–1.46, are enriched in SiO2, K2O, and Rb, and are depleted in Nb, P, Ti, …

Abstract For most rare-metal pegmatite fields, two generations of granitic pegmatites are documented, namely, beryll-bearing (often with tantaloniobates and muscovite, which are inseparable from vein granites of the leucogranite complex), and Na-Li (Li, Ta, Cs, Be, and Sn) (LCT-pegmatites). The latter, in turn, subdivide into (i) a "multicomponent rare-metal …

2.1 The U–Pb System. On first approximation, both naturally occurring long-lived parent uranium isotopes (238 U and 235 U) decay to stable lead isotopes (206 Pb and 207 Pb, respectively) at distinct rates, and thus have different half-lives and decay constants (λ 238 and λ 235).Details of the U decay to Pb are actually more complex and involve a long …
